<P>PROBLEM TO BE SOLVED: To provide a battery device that includes a plurality of battery packs to be attached to an electric tool main body as one power source, and is provided with an engagement structure for maintaining a slide attachment state of the battery device to an electric tool main body while considering compactification of the battery device. <P>SOLUTION: A main body attachment part 40 is provided with an engagement structure 51 to be engaged with a lawn mower main body in a slide attachment state when slidably attached to an attachment part of the lawn mower main body by a slide structure. Due to this engagement structure 51, the slide attachment state of the battery device 10 to the lawn mower main body can be maintained. A pressing operation surface part 56 provided to the engagement structure 51 is formed in a planar shape extending in a slide attachment direction at the slide attachment of the battery device 10 to the lawn mower main body. In addition, this pressing operation surface part 56 is formed by having a planar shape extending in a direction orthogonal to a projection direction of a male hook part 53. <P>COPYRIGHT: (C)2013,JPO&INPIT |
